Ultra Small Angle X-ray Scattering Diffractometer with photon detection

The device is capable of measuring ultra-small, small and wide angle x-ray scattering patterns of a large variety of materials such as polymers, different types of macro-molecules, oxide materials and nanomaterials (powders or thin films). With a large angular range necessary for hierarchical structures, the technique is bridging the gap between imaging and atomic resolution (below 1 µm and above 10 Å). The ultimate performance, versatility and large range of sample environments of the equipment make it a unique solution to support many applications such as: polymer phase transformation; determination of polymer crystallinity; low detection limit of crystallinity; protein structure resolution; silk fiber nanostructure investigation; investigation of gold nanoparticles etc.

Displacement range for the X axis (horizontal and perpendicular to the basic axis) = 45mm (+/- 22.5mm).
Y-axis travel range (parallel to the base axis) = 25mm (+/- 12.5mm).
Displacement range for the Z axis (vertical and perpendicular to the basic axis) = 25mm (+/- 12.5mm).
Positioning resolution <1 µm.
DECTRIS PILATUS 3 300K detector mounted on a fully monitored X / Z platform (XEU-X0-D300K02-A) and (XEU-X8-DSTD02A).
Integrated SAXS detector, 2D X-ray detector (made in Switzerland by DECTRIS), state-of-the-art PILATUS3 model, 300k pixel resolution with photon counting, is state-of-the-art solid-state, using solid-state sensors and reading CMOS in ASICs format (CMOS read-out ASICs) in hybrid pixel technology. This guarantees superior dynamic range (6 decades), very low black readings and background noise, fast reading time of up to 7 ms, PSF <1 pixel, fără să fie nevoie de reumplere periodică cu gaz. datorită amplificatorului cmos, fiecare pixel lucrează la viteze numărare>no need for gas refilling. Thanks to the CMOS amplifier, each pixel works at counting speeds > 106 counts / s. Because each pixel counts individually, it leads to total rates> 3.4x10 ^ 9 / cm2. The detector operates in the air.
The detector is assembled on a motorized X / Z system that allows it to be collected from wide angles by off-center positioning of the detector.
The Xeuss 2.0 system in our offer integrates a second hybrid pixel detector for simultaneous SAXS and WAXS measurements. This second detector is positioned in the vacuum sample measuring chamber and can measure WAXS signals at angles up to 2theta = 60º.
The detector is of DECTRIS production, with the sensor of 320 μm2, sensor size 83.8x33.5 mm2 and format 94,665 pixels.

X-ray fluorescence equipment/ spectrometer XRF

The Thermo Scientific ARL PERFORM’X X-Ray fluorescence (XRF) sequential spectrometer presents an advanced platform for rapid and precise analysis of up to 90 elements in nearly any solid or liquid sample. The advantages of this analytic technique are: easy and fast sample preparation; analysis of the whole surface of a sample, a segment of it or specific spots on the surface; speed of analysis; high stability and excellent precision; wide dynamic range (from ppm levels to 100%).

The ARL PERFORM’X spectrometer will solve composition problems in demanding industrial processes and quality applications in industries as diverse as food, cement, glass, refractories mining, polymers, petroleum and metallurgy. Academic or research labs dealing with food safety, materials science, environmental research, forensics, geochemistry and automotive engineering may benefit from its performance and versatility.

Freeze drier

The EPSILON 2-90 is a single-chamber system in which the freezing-depressurizing-sublimating processes occur for very high quantities of substance in order to eliminate the solvent within the material without affecting its solid structure. The chamber holds 14 shelves with a total surface of 11.3 m2, with a 33 mm distance between two consecutive shelves, fact that assures a vertical thermal homogeneity. The ice condenser can withstand to 90 kg of ice, its performance being 75 kg / 24 h.

Due to its simple construction, it can be easily used in areas such as the food industry (dehydration of fruits, vegetables, dairy products, plants, spices, etc.), the pharmaceutical industry (removal of solvents from pharmaceuticals) or for preserving materials (archeological objects, drying books, etc.).
